v1.278.2
Bug fixes
Allow the page view feature to have access to an event buffer
Fix an issue where if the page unloaded before the page view feature could "block" itself from future harvests, an undefined error could be thrown when the harvester tries to access each feature's event buffer. The page view feature now has access to the event buffer, to prevent that undefined check. The event buffer will remain empty, since the page view feature does not carry state. This change rectifies an issue observed in 1.278.1.

v1.278.0
Features
Centralized harvesting
Introduces a singleton harvester tasked with sending feature payloads rather than each feature utilizing their own scheduler. This reduces runtime space usage and the number of timers which proportionally scales as the number of features increases.

v1.277.0
Features
Add custom events API
Add a new API - recordCustomEvent(eventType, attributes). This allows any custom-defined eventType to be stored in NRDB. Check the API documentation for more information.
Bug fixes
Soft navigation bug fixes and new soft navigation tests
Fixes several issues tied to the soft navigations feature. Calling newrelic.interaction() prior to a page load now creates a separate "api" trigger node. Multiple interactions managed simultaneously now have correct timings. Fixes a bug in soft navigation, where API-triggered interactions fail to close under default heuristic (URL + DOM change), because the mutation observer is not started. Finally, 'popstate' events are now valid interaction triggers for soft navigations.

v1.276.0
Features
Allow feature flags to control experimental features
Use internal feature flags to control experimental features, reducing your effort and supporting APM-injected installations.
Capture Page Resource Assets
Add detection for page resource assets that captures data as a BrowserPerformance event. This feature is being shipped in an experimental state and is off by default. To opt in to using this feature, it can be turned on by setting the config value init.performance.resources.enabled = true in Copy/Paste or NPM installations.
Bug fixes
Ignore reserved attribute names on UserActions tied to the window
Force the agent to not capture target-level attributes for window-level UserActions. You can set window-level variables that mimic HTML element attributes like type or tagName. This change prevents the potential capture of those attributes as part of blur or focus user actions tied to the window.
Fix syntax error in fallback when tracking xhr readyState
Fixed the syntax error that would cause xhr readystate fallback checks to always capture.

Enable the browser agent to run in extension background contexts
Use fetch to send harvest payloads when XMLHttpRequest is unavailable, such as in browser extension contexts.
Bug fixes
Harvest generic events when max size is reached
To avoid behavior that could lead to more network requests than necessary, generic events will now harvest early when the max payload size is reached. This represents an increase from 64Kb to 1Mb.

Upgrade underlying session replay libraries to latest version which addresses some known bugs.
